Problems solved by technology

However, due to the heat leakage of the cryogenic container itself and the conduction heat of the current lead, it is necessary to continuously replenish liquid nitrogen, and the working temperature of the magnet is around 77K, which cannot meet the requirements of the 30K temperature zone.
[0006] 2. Direct conduction cooling of superconducting magnets through cryogenic refrigerators. This method is simple and direct, but it cannot be applied to rotating superconducting motor rotating components 1-2, especially when the line speed is high
[0008] Publication No. CN104502843B discloses a patent for the invention of a superconducting low-temperature rotary test bench. The rotary test bench is designed for single-end rotation, and the state of superconducting materials and wrapping materials is tested when the superconducting motor is in the rotating state. Although it is also a test Superconducting motors at low temperature are not suitable for internal leakage rate test of refrigerant transmission coupling devices

Abstract

The invention discloses a test system of a refrigerant transmission coupling device. Through the design of the bellows assembly and the sliding track, the refrigerant connection pipeline can be quickly disassembled, and the static assembly can be quickly replaced without greatly dismantling the equipment, realizing different The rapid replacement of the samples to be tested not only ensures the assembly accuracy of the equipment, but also saves time and improves work efficiency. The long-stem cryogenic valve is used as the turning point of the return air passage, which can not only demonstrate different openings according to the requirements, simulate the flow resistance load of different rotors, but also rotate with the system to realize the simulation of different speeds, satisfying the coupling of refrigerant transmission for different models to be tested. Device testing requirements. The test system provided by the present invention is used to test the efficiency of the refrigerant transmission coupling device, which is proposed for the first time in the technical field of refrigerant transmission coupling device testing.
